Bill,
Great topic, here are some excellent ones I've been lucky enough to get my hands on;
Waterloo by Lachouque; THE book on the battle for artwork, if there is another as good as or better, let me know.
Napoleons War in Spain by Lachouque; again, THE book on the Peninsular Campaign, loaded with great artwork.
On Campaign in the Age of Napoleon, the works of Keith Rocco; a top shelf artist, one of the best if not the best of his generation, covers a variety of topics, beautiful book.
1813- La Campagne d'Allemagne by Jean Tranie; covers the German campaign of 1813
1814-La Campagne De France by Jean Tranie; covers the 1814 French Campagin.
1812-La Campagne De Russie by Jean Tranie; covers the 1812 Russian Campaign.
He has written several other books, the 1805 campaign, the 1806 campaign, the 1807 campaign, the 1809 campaign among them, terrific books loaded with artwork. All of his books are in French, are out of print, but can be found via searching the internet, several of his works command 500.00 or more.
My two most favorite titles in closing;
Napoleon En 1814 by Koch; covers the French Campaign.
Napoleon En Allemagne by Clement; covers the 1813 Campaign.
These two books are massive volumes, each with 600+ pages, the artwork in both is staggering, one terrific painting after another. Both are in French, but who cares, the artwork is the thing with these, both published by Le Livre Chex Vous out of Paris, well worth the price, both are still in print.
Interested to see what others come up with, Napoleonic artwork is one of my passions........
